Ptychodus is a genus of extinct hybodontiform sharks. As well as a genus of durophagous (shell-crushing) sharks from the Late Cretaceous. Fossils of Ptychodus teeth are found in plenty in many of the Late Cretaceous marine sediments. There are many species among the Ptychodus that have been uncovered on all the continents around the globe. Such species are Ptychodus mortoni, P. decurrens, P. marginalis, P. mammillaris, P. rugosus and P. latissimus to name a few. They died out approximately 85 million years ago in the Western Interior Sea, where a majority of them were found. A recent publication found that Ptychodus are classified as neoselachian versus hybodont or batoid.
